Establishment of the dorsal-ventral axis of the Drosophila embryo:
A)involves the production of localized DL mRNA on the ventral side of the developing embryo.
B)occurs via at least two paracrine signals transmitted between the developing oocyte and the surrounding somatic follicle cells.

The establishment of the dorsal-ventral axis in the Drosophila embryo involves interactions between the developing oocyte and the surrounding somatic follicle cells, which include the transmission of at least two paracrine signals. These signals are crucial for determining the orientation of the dorsal-ventral axis.
